Hi, I am using RSPerl package on Ubuntu and Apache2 web server. It is my first experience with R language :-)
I have the next code embedded into a Perl CGI: use R; use RReferences; my @x; &R::initR("--silent","--no-save"); &R::library("RSPerl"); @x = &R::call("rnorm", 10); &R::call("plot", [EMAIL PROTECTED]); The CGI works but no plot is shown. Apache2 web server log says: [Sun Jun 22 12:01:41 2008] [error] [client 127.0.0.1] Error in pdf() : unable to start device pdf, referer: http://localhost/html/proveta.html [Sun Jun 22 12:01:41 2008] [error] [client 127.0.0.1] In addition: Warning message:, referer: http://localhost/html/proveta.html [Sun Jun 22 12:01:41 2008] [error] [client 127.0.0.1] In pdf() : cannot open 'pdf' file argument 'Rplots.pdf', referer: http://localhost/html/proveta.html [Sun Jun 22 12:01:41 2008] [error] [client 127.0.0.1] Caught error in R::call(), referer: http://localhost/html/proveta.html However, if I use R directly plots are correctly shown. Can anybody help me? Thanks! Josep Lluís Figueras (from Barcelona) [[alternative HTML version deleted]]
